RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Punit Kundal 2016-05-12 10:22:09 UTC 
Description of problem:

Modifier's name is not recorded in the audit log with modrdn and moddn operations

Version-Release number of selected component (if applicable):

RHEL Version:
RHEL 7.3 x86_64 Server
 
DS Version:
389-ds-base-libs-1.3.5.3-1.el7.x86_64
389-ds-base-1.3.5.3-1.el7.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Create a new DS instance
 
2. Enable audit logging
 
3. Add a user entry as below
 
[root@corp ~]# ldapadd -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
objectclass: top
objectclass: person
objectclass: inetorgperson
uid: tuser
cn: test user
sn: user
adding new entry "uid=tuser,ou=people,dc=example,dc=com"
 
4) Perform a modrdn operation on the entry as below
 
[root@corp ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=people,dc=example,dc=com
changetype: modrdn
newrdn: uid=testuser
deleteoldrdn: 1
modifying rdn of entry "uid=tuser,ou=people,dc=example,dc=com"
 
5) Check the audit log in /var/log/dirsrv/slapd-corp/ directory, only this information is recorded
 
time: 20160512143153
dn: uid=tuser,ou=People,dc=example,dc=com
result: 0
changetype: modrdn
newrdn: uid=testuser
deleteoldrdn: 1
 
as can be seen, the modifiers name is missing here
 
6) Perform a moddn operation on the entry as below
 
[root@corp ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=testuser,ou=people,dc=example,dc=com
changetype: moddn
newrdn: uid=tuser
deleteoldrdn: 1
newsuperior: ou=groups,dc=example,dc=com
modifying rdn of entry "uid=testuser,ou=people,dc=example,dc=com"
 
7) check the audit logs
 
time: 20160512143829
dn: uid=testuser,ou=People,dc=example,dc=com
result: 0
changetype: modrdn
newrdn: uid=tuser
deleteoldrdn: 1
 
again, the modifiers name is missing here


Expected results:

The modifier's name should be recorded in the audit logs with modrdn and 
moddn operations

Comment 4 Punit Kundal 2016-06-23 14:20:46 UTC 
The change type recorded in the audit log for moddn operation on an entry is modrdn, here are the steps performed:

1. Modified the dn of the entry
[root@ds ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=testuser,ou=People,dc=example,dc=com
changetype: moddn
newrdn: uid=tuser  
deleteoldrdn: 1
newsuperior: ou=Groups,dc=example,dc=com
modifying rdn of entry "uid=testuser,ou=People,dc=example,dc=com"

As can be seen, I've changed the rdn of the entry as well the the 
subtree to which it belongs.

2. Checked the audit log file
[root@ds ~]# tail -f /var/log/dirsrv/slapd-supplier/audit
time: 20160623153022
dn: uid=testuser,ou=People,dc=example,dc=com
result: 0
changetype: modrdn  #The change type is modrdn
newrdn: uid=tuser
deleteoldrdn: 1
newsuperior: ou=Groups,dc=example,dc=com
modifiersname: cn=directory manager

Is this correct?

It's an easy fix.  Reopening a bug...

Comment 6 Noriko Hosoi 2016-06-23 23:13:45 UTC 
Sorry, let me take back my previous comment #c5.  The changetype moddn is an alias of modrdn.  So, the server does not distinguish them.  Internally, there is only one operation which is MODRDN (e.g., the following log messages are from the access log.  So, please ignore the difference in the audit log, too.

dn: uid=tuser0,ou=People,dc=example,dc=com
changetype: modrdn
newrdn: uid=tuser00
deleteoldrdn: 1

[..] conn=6 op=1 MODRDN dn="uid=tuser0,ou=People,dc=example,dc=com" newrdn="uid=tuser00" newsuperior="(null)"
[..] conn=6 op=1 RESULT err=0 tag=109 nentries=0 etime=0

dn: uid=tuser00,ou=People,dc=example,dc=com

[..] conn=8 op=1 MODRDN dn="uid=tuser00,ou=People,dc=example,dc=com" newrdn="uid=tuser00" newsuperior="(null)"

Thanks.

389-ds-base-libs-1.3.5.6-1.el7.x86_64

Following are the steps performed for verification:
1. Enabled audit logging on a standalone DS instance
[root@ds ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: cn=config
changetype: modify
replace: nsslapd-auditlog-logging-enabled
nsslapd-auditlog-logging-enabled: on
modifying entry "cn=config"

2. Added a user entry
[root@ds ~]# ldapadd -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=People,dc=example,dc=com
objectClass: top
objectClass: person
objectClass: inetOrgPerson
uid: tuser
cn: test user
sn: user
adding new entry "uid=tuser,ou=People,dc=example,dc=com"

3. Modified the rdn of the entry
[root@ds ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=tuser,ou=People,dc=example,dc=com
Changetype: modrdn
newrdn: uid=testuser
deleteoldrdn: 1
modifying rdn of entry "uid=tuser,ou=People,dc=example,dc=com"

4. Checked the audit log file
[root@ds ~]# tail -f /var/log/dirsrv/slapd-supplier/audit
time: 20160623152639
dn: uid=tuser,ou=People,dc=example,dc=com
result: 0
changetype: modrdn
newrdn: uid=testuser
deleteoldrdn: 1
modifiersname: cn=directory manager

5. Modified the dn of the entry
[root@ds ~]# ldapmodify -x -D 'cn=Directory Manager' -w secret123 -h localhost -p 389
dn: uid=testuser,ou=People,dc=example,dc=com
changetype: moddn
newrdn: uid=tuser  
deleteoldrdn: 1
newsuperior: ou=Groups,dc=example,dc=com
modifying rdn of entry "uid=testuser,ou=People,dc=example,dc=com"

6. Checked the audit log file
[root@ds ~]# tail -f /var/log/dirsrv/slapd-supplier/audit
time: 20160623153022
dn: uid=testuser,ou=People,dc=example,dc=com
